ACETYLENE-GAS GENERATOR.

SPECIFICATION forming part of Letters Patent No. 661,761, dated Noveniber 13, 1960.

Application filed February 26, 1900. Serial No. 6,528. oramdl.)

To all whom it may concern.-

Be it known that I, WILLIAM S. HAMM, a citizen of the United States, and a resident of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Acetylene-Generators,of which the following is a specification and which are illustrated in the accompanying drawings,

.complished and'the inspector must be able to determine accurately the condition of the charge.

The object of the invention is to provide means for determining the extent to which the chemical action has proceeded withinthe generating-cell by means of the state or stage of the water within-the reservoir or tank; and this object is attained by the construction hereinafter fully described and which is illustrated in the accompanying drawings, in which- Figure 1 is a detail side elevation of an acetylene-generator. Fig. 2'is a detail front elevation of the reservoir of the same, partly in section. Fig. 3 is a sectional view on the line 3 3 of Fig. 2. Fig. 4 is a detail front elevation of the generator, some of the parts being removed.- Fig. 5 is a detail section on the line 5 5 of Fig. 1, and Fig. 6 is a plan section on the line 6 6 of Fig. 4.

The particular form of generator is not essential to the presentinvention. For the purpose of illustration I have shown the gener ator invented by John A. Mosher and forming the subject of a concurrently-pending application for Letters Patent.

The generating-cell is shown at 10. andthe The water-feed being through the dome of.

the generating-cell is delivered on top of the carbid, and the chemical action proceeds thence downward gradually until all of the carbid is reduced, there being no chemical action set up in the lower compartments of the basket until all of the compartments'above have been exhausted. The water-tank and the carbid-basket are so proportioned relatively that the state or stage of water within the tank, both the tank and, basket having been filled at the commencement of theoperation, will at all times indicate the extent to which the chemical action has been carried in the basket. A suitable water-gage 23, of

any preferred form, is applied to the tank and is provided with a scale corresponding with the compartments of the basket 16. In the device as shown in the drawings the basket being subdivided into four co ll] partments the water-gage is correspondingly scaled, and when the carbid in the upper compartment 17 of the basket has been completely slaked the water will have fallen to the upper mark on the scale of the gage.

This invention is especially serviceable in connection with generators in which there is employed a plurality of generating-cells, as it enablesthe inspector to determine at a glance which of the cells require to be recharged. In railwayftrain lighting provision is made at certain stations toinspect the generator and to replace exhausted cells with others newly charged and to refill the watertanks. y I 1 I claim as my invention V I In an acetylene-generator, in combination,

a fixed nipple, a generating-cell removably' to indicate the quantity of waterreqniredf or attached thereto and having a plurality of sla-king the contents'of each carbidrecep vertically-arranged carbid-reeeptacles, the I tacle.

nipple and cell being s0 f0rrned that. water 7 WILLIAM S. HAMM. will be delivered upon the top of the carbid, In presence ofa water-tank and connection leading there- E. M. KLATGHER,

from to the nipple, and a. Water-gage sealed PAUL CARPENTER.
